Magnetized Dusty Black Holes and Wormholes
Universe, 2021 We consider the generalized Tolman solution of general relativity, describing the evolution of a spherical dust cloud in the presence of an external electric or magnetic field. The solution contains three arbitrary functions f(R), F(R) and τ0(R), where R

Does gravity induce wavefunction collapse? An examination of Penrose's conjecture [PDF]
, 2013 According to Penrose, the fundamental conflict between the superposition principle of quantum mechanics and the principle of general covariance of general relativity entails the existence of wavefunction collapse, e.g.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Physics of Collapse and Terminating Events [PDF]
, 1997 Various catastrophic phenomena, including the sawtooth, ELMs, High-beta collapse, etc., have been known in plasmas. The large scale deformation and transition take place abruptly, characterizing the spatio-temporal evolution of the plasma structure.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

La argumentación jurídica en la toma de decisión judicial
Revista Vasca de Administración Pública, 2014 The judicial decision making is not only a mental activity but it has an argumentative part that if it is taken into account can improve the decision. A theory about the legal reasoning that deals with the context of discovery allows to establish in a ...

Self-gravitational system. New approach
Condensed Matter Physics, 2006 The field theory approach to statistical description of the system of gravitational interacting particles is proposed in order to describe spatially inhomogeneous structures.

In the Climate Emergency, Conservation Must Become Survival Ecology
Frontiers in Conservation Science, 2021 Earth faces a climate emergency which renders conservation goals largely obsolete. Current conservation actions are inadequate because they (i) underplay biodiversity's role in maintaining human civilisation, which contributes to its marginalisation, and

Epigenetic reprogramming of lineage switching in cancer
FEBS Letters, EarlyView.Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using
